My wife just got an Optimus V on 6/27. The past few days, the phone will not stay in a charging cycle at all. Doesn't matter if it's via the wall charger, the USB port on the pc or the car charger. It will connect and charge maybe a few percent then stop. Sometimes it will charge 15 or 20 percent and then stop. Last night we left it on the laptop to charge...it went from 26% up to 49% and then stopped. If you unplugged it and replugged it back in it would start charging again and then stop about a minute later. I went ahead and left it on overnight. My wife says it was up to 100% this morning. My question is is this a sign of a bad battery, charging port on the phone, or bad cable or what? I did check voltage on the battery pack out of the phone when the charge was around 23% and it was showing 3.74 Volts. I'm not sure of what else to try but sure seems strange it started happening all of a sudden. I have a blackberry charger with a solid mini usb (not the detachable usb) with similar voltage output and it even did the same starting and stopping with that charger as well. I'm stumped.
